Suppose you have a disk that has 400 cylinders numbered 0 to 399. The disk head is currently at cylinder 154 NOTE: the previous serviced request was at 28, that should tell you the direction!) (note: C-SCAN is implemented to service requests in the direction from 0->399) The queue for requests to be serviced looks as follows: 94, 283, 38, 112, 14, 324, 65, 267,Given this information, for the following algorithms:a) SSTFb) C-SCANc) FCFSd) SCANGive the order which the requests in the queue will be processed for each algorithm and calculate the TOTAL distance in cylinders that the read head traveled to satisfy all of the remaining requests.
